About our electronic leak detection in Bishop's Waltham
Electronic leak detection, or ELD, finds holes in flat roof waterproofing membranes. It uses a small electrical current that passes through the membrane only where there’s a breach. That lets us locate holes that are too small to see so your roofer knows exactly where to repair. You get a written report with photos of each breach found. If you are worried about holes left by work on the roof and new membranes needing a check before handover, we can find out what’s behind it, whatever the roof.
Around Bishop's Waltham, many homes have a garden room, garage or outbuilding with a flat roof. They’re rarely looked at until something gets wet. It is worth mentioning them as you book, so the visit can include them, along with the main flat roof. Felt, rubber and GRP coverings on garages and outbuildings age in just the same way as the main roof’s.
It is not only a list of defects. For each finding, it explains what it is, why it matters and what we’d recommend, so you can plan your next steps.

Electronic leak detection around Bishop's Waltham
A number of Hampshire villages keep thatched roofs on their older buildings. Across the South East, older homes tend to have slate or clay tiles, and many later ones concrete tiles. Next to the main roofs there’s normally a flat roof somewhere, whether on an extension, a garage or a commercial unit. Older buildings may be listed or sit in a conservation area. Historic England’s list shows listed buildings, and the council can say whether a street is in a conservation area. In either case, a change of roofing material may need consent.
If you live in an older home near Church of St Peter, the flat roofs on later extensions tend to wear out long before the main roof. For landlords with property near Botley station, flat roofs over rear additions and dormers in rented property are worth checking between tenancies.

For landlords and managing agents

Buyers’ agents can book surveys on behalf of their clients. The report is emailed, so it can go straight to your client, photographs included.
Signs you need electronic leak detection in Bishop's Waltham
If a flat roof keeps leaking after patching, the hole may be elsewhere. Electronic testing helps pinpoint it.
These are some of the problems a survey can pick up:
- Leaks showing away from the breach
- Leaks through a covered membrane
- Leaks through a flat roof with no obvious cause
- Punctures from foot traffic or tools
If you look after a building such as Bishop's Waltham Junior School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

What else we do in Bishop's Waltham
What a survey costs
The price reflects the time and kit the roof needs. The main factors are:
- The height of the building and how the roof can be seen safely
- Extra roofs, like extensions, dormers or garages
- How big the roof is
- Features like valleys, chimneys, dormers and parapets
All our prices include VAT. We quote electronic leak detection for each roof, as the method and time depend on the roof. We confirm the price for your survey before booking.
Getting in touch
These details help when you contact us:
- When you need the report by
- How the loft is reached, if there is one
- Why you want a survey: buying, a leak, a storm or new work
- Where the property is, with the postcode
Buyers should book once an offer has been accepted, so there’s time to use the report before exchange. For any other survey, just phone 07833 053749 or use the contact form when you are ready.
Common questions in Bishop's Waltham
Does a conservation area affect roof work in Bishop's Waltham?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it is in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Is Bishop's Waltham within the area you cover?
Yes, Bishop's Waltham is on our map. Villages and rural addresses get the same survey as a town house.
How do I arrange electronic leak detection in Bishop's Waltham?
It is easiest to call 07833 053749 or email us. Let us know the address and a little about the roof, and we will point you to the right survey. We survey on any day of the week.
What does electronic leak detection do?
The waterproofing membrane normally stops an electrical current, but a hole lets it through. That lets us find breaches that are too small to see.
Do you survey roofs on blocks of flats?
Yes, once access has been agreed. The roof of a block or converted house is frequently shared, so the freeholder or managing agent needs to agree access. We inspect only the parts we are allowed to reach.
How many surveys have you done?
Over 20 years and more than 5,000 surveys, across London and South East England.
How much time does ELD need?
The roof’s size and build-up decide how long it takes. You will know roughly how long before we start.
How the survey works
Where it is relevant and can be reached safely, the roof space is checked as well as the outside. In the loft, the signs we look for are staining, damp, daylight and sagging, as far as the space allows. All in, the survey usually takes a length of time set by the size of the roof and how it’s built, which we set out in the quote. A visit to a smaller place like Bishop's Waltham is no different on the day: outside, inside and from any safe vantage point, in that order. Point out any stains, cracks or loose pieces you’ve spotted.
- You tell us about the roof and where water is showing.
- The roof is assessed for suitability first.
- The test method is chosen to suit the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Before the survey
- Buyers: confirm access with the estate agent or seller
- Keep pets out of the way during the survey
- Let us know about any leaks, stains or damp patches you know of

Advice
Before and after the survey
Some practical points come up on survey after survey. They apply to most roofs:
- Do not let outlets block
- Test new membranes before covering them
- Stay off the flat roof unless needed
- Note where leaks show inside and when
Once repairs are made, the roof can be tested again if you want to check them if the build-up allows.
ELD before paving, ballast or planting goes on is worth considering. It is easier to find holes before more layers are added.
Roof by roof
EPDM rubber roofs
Certain rubber membranes are conductive which can limit electronic testing. We will say if the test won’t work.
Bituminous membranes
ELD is often possible on bituminous membranes, depending on what’s below.
